The Chief looked tired, but much happier than the last time he came in. Must have been the coffee. – “Looks like we are getting close to something here sonny!”

We need some sort of identifier for this guy! If only we knew his phone number…”

I nodded. “I’ll see what I can do Chief, give me an hour.”
